LIQUID-DISPENSING- VESSEL. I

Application filed January 21, 1908. Serial No.; 41'1,963.

T 0 all whom it may concern:

Be it known that I, Lnwrs G. LANGSTAFF,

,The object of my inventionis toprovide,

a very simple and effectivedevice for insuring the deliveryof a predetermined'quantity ofliquid from 'a vessel and it is more particularly directed to vessels arranged to dis- 'Tpenseliquid soap. In the accompanying drawings, Figure 1 atop plan view ofmy im roved vessel and the meansfor supporting t e same, Fig. 2 is aside view of the same partially in vertical centralsection, Fig. 3is a detail'vertical centralsection showing the position of the parts when the vesselis raised for dispensing the liquid, Fig. 4 is a detail verticalcentral 886-. tion taken at the top of the vessel and show-- ing a portion of its supporting bracket, the

.filling cover being shown moved back to open communication to the interior of the vessel, Fig. 5 is a detail top plan-view or the same,

and Fig. 6 is an enlarged detail side view of the-valve and its disk.

The vessel-is herein. re resented as of a hollow lspherical form an is denoted by 1'.

This vessel is provided atiits bottom'with a lieuid dispensing chamber-2 having a cen-' I tral y arranged discharge port 3, The liquid dispensing chamber is formed by providing the vessel 1 with a centrally arranged verti-' .cal tube 4, the lower end of which tube pro- Ijects through the bottom of the vessel and is there engaged by a screw threaded cap 5 which forms the bottom of the dis ensing chamber. This cap is provided wit hand engaging lugs 6 projecting downwardly a distance below the head of the valve 7. The

stem of the valve 7 is provided adjacent to its head with an enlarged portion 8, which closely fits the discharge port 3, and a re-' duced portion 9 of less diameter than the said port.

The bracket which supports the vessel comprises a lateral arm 10 arranged to .be 'sethired to the wall or other suitable support and a depending tubular arm 11 which extends downwardly into the vessel 1 within the-tube 4 and forms the'pist on forejecting a "predetermined quantity of the liquid from Specification of Letters Patent.

provide a filling opening exterior tothe' vessel 1.

- A springpressed-sliding cover'12 is'located on the lateral-arm 1.0 of thebracket in position to normally close the upper end of the.

hollow piston 11, a spring 13 being provided which is lnterposed'between the cover 12 and a shoulder on the arm 10. A 'disk '14 is looselymounted'in.the lower end of the (lepending arm 11 of thebracket on a cross pin 115, the'hole extending diametrically through the disk, through which the pin 15 passes being larger than the pin and the disk'being of less diameter than the bore of the tubular arm so as to permitthe disk to have a 'li'mited lateral movement in all directions. The valve 7 forms a rigid part ofthe oisk 14 and the disk 14 forms. the piston head. The

- sures the proper seating of the valve Z.

The interior of the hollow piston is open to the interior of the vessel through lower holes 16, 17, and upper holes 16*, 17*, in the depending tubular arm and the tube 4 respectively, for permitting the liquid "to flowfreely from the interior of the hollowpist'on --11 into the interior of the vessel when the vessel is being filled. The dispensingchamher 2 is open to the interior of the vessel when the vessel is'in'its normal lowered position-througha port 18 in thetube 4, which port is closed by the hollow piston as the vessel is raised for dispensing the liquid from the said chamber.

In operation, when it is desired to dispensea portion of the liquid from within the vessel, the vessel is raised by the engagement of the hand with the lugs 6 of the cap 5. The first part of the upward movement of the vessel will serve to close the port 18. During this portion of the upward movement of the slight lateral movement of the. disk 14 in-.

iio

will also be seen that the entire weight of the vessel is taken upon the valve 7 when the parts are in their normal position thus furextended ther insuring an absolute closure of the dischar e port.

W at IFclaim is l i g 1. A vertically movable liquid containing vessel, a tube extended therethrough having a dispensin'g chamber at its lower end and a discharge iport therefor, a stationary piston o'wn into the said tube and a discharge port'ivalve carried by the piston.

2. A vertically movable liquid containing vessel, a tube'extended therethrough having a dispensing chamber at its lower end and a discharge ort therefor, a stationary piston extended own into the said tube and a discharge port valve carried by the piston and movable laterally with respect to the piston.

3. A vertically movable liquid containing vessel, a tube extended therethrough having a dispensing chamber at its lower end and a discharge port therefor, a stationary hollow piston extended down into the said tube and a discharge port valve carried by the piston, the said piston having a filling hole therein exterior to the vessel. v

'4. A vertically movable liquid containing vessel, a tube extended therethrough having iii dispensing chamber'at its lower end and a discharge port therefor, a stationary hollow piston extended down into the said tube, a discharge port valve carried by the piston, said piston having a filling hole therein exterior t0 the vessel, and a cover for said filling hole.

5. A vertically movable liquid containing v vessel, a tube extended therethrough and projet'rting below the bottom of the vessel, a cap secured to the lower end of the tube to form a dispensing chamber, a discharge port in the said cap, a stationary piston extended down into the tube and a discharge port valve carried by the piston.

6. A vertically movable liquid containing vessel, a bracket for supporting the vessel comprising a lateral arm arranged to be socured to the wall or other su )port, and a depending tubular arm exten ed downwardly lnto thelvessel to form a piston, a tube extended through the vessel having a dispensing chamber at its lower end and a discharge port therefor, and a discharge port valve carried by the piston.

7. A vertically movable liquid containin I vessel, a bracket for supporting the vesse comprising a lateral arm arranged to be secured to the wall or othersu )port, and-a depending tubular armexten ed downwardly into the vessel to form a piston, a tube extended through the vessel having a dis )ensing chamber at its lower end and a discharge port therefor, and a dischar e )ort valve carried by the piston, the said 0 low iston being 0 arm at its up erend to provir e a filling hole ior the vesseii i i i 8. A vertically movable liquid containing vessel, a bracket for supporting the vessel comprising a lateral arm arranged to be Secured to the wall or other su )port, and a deending tubular arm extended downwardly into the vessel to form a )iston, a tube extended through the vessel aving a dis ensing chamber at its 10 or end and a disc large port therefor, and a (Iischar e ort valve carried by the piston, the said 0 low iston being 0 en at its upper end to provi e a filling hole or the vessel, and a sprin ressed cover carried by the bracket for sai iilling hole. In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this seventeenth day of January 1908.
